It is situated in the high ground known as the Uldale Fells, 5.5 kilometres south west of the village of Caldbeck.
It reaches a height of 483 m (1,585 ft) and it is (along with Binsey) the most northerly fell in the Lake District.
The Longlands Fell copper mine operated in the second half of the 19th century but was soon found to be uneconomical and abandoned, one of the levels is now dammed to provide water to the village of Uldale.
Longlands Fell is one of the easier fell walks in the Lake District, the ascent starts from the hamlet of Longlands, which is a small group of houses and takes the track north east which skirts the base of the fell, this is part of the low level alternative of the Cumbria Way, when the foot of the northern ridge is reached this is followed up easy slopes to reach the summit.
The view from the top takes in the Solway Firth and the Galloway hills to the north.
